> Skill based on Aave V3 Core (contracts as of 2026-02-09), generated from `sources/aave-v3`. Note: repo is deprecated; latest V3 lives at [aave-dao/aave-v3-origin](https://github.com/aave-dao/aave-v3-origin). This skill still applies to the core interfaces and patterns.

Aave V3 is a decentralized liquidity market: supply assets to earn yield, borrow over- or under-collateralized. Core entry is **IPool** (supply, withdraw, borrow, repay, liquidation, flash loans). Use **IPoolAddressesProvider** to get Pool and oracle/configurator addresses per market. **DataTypes** define reserve and user config bitmaps and structs. **Flash loans** use IFlashLoanReceiver / IFlashLoanSimpleReceiver. **eMode** and **isolation mode** affect LTV and which collateral can back debt.
